IMPROVEMENTIN- COOLING AIR AND OTHER SUBSTANCES- Specification forming part of Letters Patent No. 70,909, dated November 12, 1867.

To all whom it may concern:

Be it known that I, DANIEL E. Sons, of Washington, District of Columbia, have invented a new and Improved Process and Apparatus for Cooling Air and Buildings; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings making part of this specification.

Buildings for cooling purposes may have an additional inner roof, A, Figures 1, 2, 3, and 4;, constructed of tin, copper, zinc, galvanized iron, or other suitable material, with its upper surface sloping gently on all sides to its outer edge, as shown in Figs. 1 and 2, around which a ledge or flange may form a gutter, from which pipes or channels B. may lead to a tank, reservoir, or water-course below. Through this roof, at or near its center, rises from the bottom of the building a tight trunk or conduit, O, forming any 'angle' deemed desirable with the horizon, down which water, previously drawn or forced up by rams, pumps, or their equivalents, or which may be supplied from a reservoir at the proper altitude, is allowed tofall and meet with obstructions in its descent, so as to be broken into foam and spray, while a blast of air from a blowing-engine is made to ascend the trunk or conduit 0, still further atomizing the water, converting it into fine mist, and thereby reducing its temperature, and carrying a portion of it out at the top of the trunk, to be deposited, in a cooling condition, on the top of the inner roof. This is shown in Figs. 1 and 2, which are vertical sections in different planes of the same building. The air between the two roofs and that which is forced up through the trunk becomes heavier-from being cooled, and falls through spaces or channels D surrounding the apartments within the building, or into such apartments, causing the warmer air to give way to it, so as to be conducted off. The condensed spray or mist, as it falls on the roof, will run, as before stated, to the edge to fall to the reservoir below, from which it may be carried up again by pumps, rams, or their equivalents, to be allowed to fall again and be broken by an ascending blast of air.

When the building is located ina city which is supplied by water-works, or at the base of a hill, where the water may be supplied from out the aid of a blower or pump to force the air upward, downward, or laterally, as the air fin this case will fall by its weight to the spaces or channels surrounding the apartments in the building.

The roof A may be so constructed as to 1.11

from its outer edge to thecenter, or to the 4 upper opening of the trunk or air-duct O, as shown in Figs. 3 and 4., so that the condensed spray or mist may run to the center after falling on the roof, and flow down the sides of the duct, to be collected in a reservoir, from which it may be taken to be used again, while the cooled air may also fall by its weight down the duct, as before stated. The vertical pipe E may be made to pass upward through the air-duct C, so as to be inclosed therein, and

have atomizing apertures or tubes throughout I the length of the duct, as well as at the top,

above the roof A, so that the air, as it falls throughthe duct, will be constantly influenced by the cooling-spray. (See Fig. 3.)

Fi 4- shows the air-duct from the inner roo A as terminating in the upper story of a building, so that the cooled air, descending from above the roof, may be received therein, and thence be distributed to or around apartments contiguous or below, while the water from the. roof may either drop directly into a cistern, F, to be used as a reservoir for the supply of water to other and lower parts of the building, or it may fall into a trough or race, G, by which it may be carried to a waterwheel, for driving a fan or other purposes, before it falls into the cistern F. A valve, H,

serves to regulate the discharge of water from the cistern.

Fig. 5 shows a device for cooling liquids or air while being conveyed in pipes or channels. The pipe I, containing the liquid or air to be cooled, is to be wrapped with tow, felt, or other fibrous material which will readily receive moisture, and as readily part with it by evaposhown in this sketch at K and K. Both pipes are inclosed in a tube or chamber, L, connnected with a fan-blower or other pneumatic device, by which the air in such tube may be drawn through it or from it, partially or entirely, aiding the ejection of the spray or mist upon the covered pipe and the evaporation from its surface, and consequently'reducing the temperature of its contents. The fan or other pneumatic device used may be placed in another apartment, as shown, and may force the cooled air drawn from the inclosing tube against and around other tow or felt or similarly covered pipes conveying liquid or air which may pass through such apartment.

Fig. 6 shows atomizi-ng-tubes so arranged that a jet of air, gas, or vapor may bedriven by a blower or fan, or any equivalent device, through one of such tubes against the jet of water or other liquid rising from the orifice of the other tube, so asto diffuse the liquid in a shower of mist or spray.

Fig. 7 shows the same device arranged to throw the mist or spray against and around tiers or coils of pipes for conveying liquids or air that will be cooled by this device, such pipes being covered or not, as may bedeemed expedient, with absorbing and evaporating materials, as before set forth, to reduce the temperature of the liquid, air, or vapor Within the pipe.

In houses for slaughtering, the carcasses are to be hung in or carried through, immediately after killing, on railways or otherwise, an apartment provided with atomizing-tubes, so arranged thatcooling-spray shall be thrown over them and cool air made to flow around them, destroying in a very short time the animal heat, and speedily bringing the meat to a proper condition for curing.

In hot weather the blood of animals is heated to a high degree, and the temperature is always increased by the excitement of the animals on being driven nearthe slaughteiing-house.

It is, therefore, important to have the heat allayed, not only in view of a more perfect and speedy cure of the meat, but the meat would be in a more wholesome condition as food than if the animals were killed with their blood at fever-heat. This object I accomplish by producing spray or a gentle mist in or near the slaughter-house, where the cattle are made to stand till they are sufficiently cooled. This spray may be accompanied by a blast of air, if desirable.

The pipes, tubes, and equivalents,.hereinbefore set forth and described, for the conveyance of water and other liquids, as well as air,

gas, and vapor, are to be provided with valves, gates, or equivalent devices, for the regulation of the supply, flow,and discharge of whatever may pass into or through them.

The water pipes-may be connected with pipes deep in the earth or in water, through which the water is made ,to flow, inorder to have it cooled by the temperature of the earth or the body of water in which the said pipes are sunk; or wells or trenches may be sunk in or near the building, with pipes connecting them, so that the water may flow up from one through one pipe, and, after it has performed its office of cooling, be directed to another through the connecting-pipes in the earth to the well or pipe from which it first started. and repeat the operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Atomizing liquids by means of a fanblower, substantially as described.

2. Cooling air or liquids, substantially as set forth. 3. The devices or their equivalents, substantially as set forth, for cooling air and liquids.
